Added calls to GC.AddMemoryPressure() when unmanaged memory is allocated for ODE (helps the GC make better scheduling choices), and a call to GC.Collect() right before logins are enabled for a region. Although this doesn't change actual memory usage, it improves the reported usage from OpenSim and the operating system
